Key Technologies for IEEE 802.11be (Wi-Fi 7)

The IEEE (Institute of Electrical and Electronics Engineers) will release a new amendment standard IEEE 802.11be - Extremely High Throughput (EHT). The new 802.11be amendment aims to achieve much faster and larger-capacity data transmission compared to the previous 802.11ax. Although 802.11be is still an upcoming standard, the Wi-Fi Alliance® clarified Wi-Fi 7 will be the next major generational Wi-Fi technology evolution based on the developing the 802.11be standard. 802.11ax is the first WLAN standard that operates in the 6 GHz frequency band. In addition to using the 6 GHz band with abundant spectrum resources and less interference from other wireless systems, 802.11ax uses OFDMA (Orthogonal Frequency Division Multiple Access) technology.

This technology enables 802.11ax to achieve higher effective throughput instead of increasing its theoretical maximum transmission rate. 802.11be will also support the 6 GHz frequency band. The goal of the standard is to provide more efficient data transmission with a larger capacity at a higher speed by expanding existing technologies as well as adopting new technologies not used by previous WLAN standards. By providing data throughput exceeding 30 Gbps with low latency over wireless communications, 802.11be is expected to be a fundamental technology for the latest applications and services, including video streaming with higher definition than 4K, augmented reality (AR), and virtual reality (VR).
